It is the same for both 12V and 24V battery until and unless the solar panel voltage is below 50V.

I have discovered a major problem with the circuit boards for this project from PCBWay. It appears that there are more than one version of the design and one of them does not work. In particular, the SCL and SDA connections are not correct, and as a result, the circuit does not work. Specifically, on the boards I received, if you follow the trace from the SCL connection for the OLED display, it connects to the SDA on the ADS1115 (labelled SCL, incorrectly), and then on to the SCL on the XIAO ESP32C (pin D5). This means that although the OLED connection would be OK, the fact that the ADS115 connection is wrong means the circuit does not work. Looking at the ADS1115 pinout, the order should be VCC GND SCL SDA ADDR ALRT A0 A1 A2 A3 The SCL is adjacent to VCC, but in this version of the board, the connection adjacent to VCC is the SDA instead. Of course this may be a version control issue at PCBWay, but when I ordered there was no indication of any variation, and my boards are labeled "DIY SOLAR PV ENERGY METER V2.0" Hopefully this may save others weeks of troubleshooting...

I'm in the process of building your monitoring system. Just received the boards from PCBWay yesterday and will start assembly in the next day or so. If I am interpreting the design correctly it appears that the board is powered by connecting the solar panel to the XL7015 which then supplies 5V. It's this correct? But, it is not clear what the function of the battery connection is, what type of battery it should be, and, how it is to be connected to the Xiao ESP32C3. Are you using the backside battery connection of the Xiao ESP32C3? How is this done since you have that chip in a header? Also, if the battery is intended to be an 18650, for example, is there enough space inside the case? Can you perhaps add some explanation either to your blog or you FB page on what the role of the battery is and how it should be used? TIA.

@@ndumisomnomiya5657 Yes, but there are some issues. First, regarding the battery connection, I never connected it. The designer did not respond to my inquiry. He also now has a version 2.1 (with no documented circuit) in which he mentions a "corrected" battery circuit. So it's impossible to know what this means. Also, SEEED indicates that for a battery connection, you must place a diode on the + connection. The problem with not having the battery is that when the solar is off, there is no backup and the circuit does not operate. It must be restarted manually. However, by far the biggest problem is the one mentioned in the next comment: the SDA and SCL connections are wrong. They should be in the order listed in that comment. I was able to get the circuit to work by scratching through one of the connections and using a jumper for the other. It now works perfectly. Finally, I've had some trouble with the unit disconnecting from Blynk. However, I suspect that's a network problem and does not reflect an issue with the design.

Also Arduino code as instructed on blog will not compile at with Arduino IDE or PlatformIO, spent hours troubleshooting and finally used an Arduino AI website to fix multiple errors in the posted code. Then finally came to life. This project needs attention, especially for beginners that are simply following instructions and there are no responses here for issues found. If I had not ordered, waited and assembled all the parts I probably would have just gave up. Unfortunate, as this is a great project - just needs some serious work before posting in my opinion.
